So Im able to spawn an actor with a particle system attached. The trouble is that my outliner seems to be filling up with these actors and they never get destroyed? What is the correct way to clean them up?
If your particle systems loop, they will not auto-destroy. In the “required” module in each emitter, set “emitter loops” to 1 (it defaults to 0, which means infinite loops).
As an addition to lackthereof0’s suggestion, you can use a Set Life Span node after you spawn the actor to ensure it is destroyed after x amount of seconds. This is useful if you want to use a looping emitter but which you want to destroy anyway. This of course works with all actors.
